Find LCM of 361,850,640,680 with Prime Factorization


2 361, 850, 640, 680
2 361, 425, 320, 340
2 361, 425, 160, 170
5 361, 425, 80, 85
17 361, 17, 16, 85
361, 1, 16, 5

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 5 x 17 x 361 x 1 x 16 x 5 = 19638400

Therefore, the lowest common multiple of 361,850,640,680 is 19638400.

LCM Formula to Find Lowest Common Multiple of 361,850,640,680

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

361 x 850 x 640 x 680 = 133541120000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

361 : 1, 19, 361

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,850,640,680, is 1.

Now, the common factors can be found like this.

361:19x 19

850:2x 5x 5x 17

640:2x 2x 2x 2x 2x 2x 2x 5

680:2x 2x 2x 5x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 5x 5x 17 = 6800

Therefore, the value for common factors is 6800.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 133541120000/(1x6800)

LCM = 133541120000/6800

LCM = 19638400

Thus, we can understand that the LCM of 361,850,640,680 is 19638400.
